Poisoning an Earth Immortal is not something a small sect like the Crimson Tiger Gang or the Qimen Palace could pull off.
Not to mention whether they have the opportunity, even if given the opportunity, they may not dare.
Provoking an Earth Immortal, their strength is insufficient to protect themselves, and no one would dare shield them after the incident.
If it indeed involves them, they must have been coerced.
The influence of the two sects is not large, but at least the Sect Leaders are Grandmaster level cultivators. Anyone who can force them to do such annihilation-worthy acts must be a significant threat.
Wu Chang's intuition tells him that this matter is likely related to Lü Changgeng or Peach Fairy.
Only an Earth Immortal would dare take action against another Earth Immortal.
